Pattern reversal visual evoked potentials (PR-VEPs) have been recorded in 50 patients with minor head injury (MHI) on days 1 and 30 after trauma and the data compared to 20 normals. None of the patients had visual complaints. The aim was to investigate a possible visual pathway affection in MHI and test the usefulness of PR-VEPs as an objective noninvasive tool in the detection of a possible subclinical affection of the visual system in MHI. P100 latency and amplitude had no significant difference compared to normals. Comparison of patient data on days 1 and 30 after trauma showed a significant latency decrease and amplitude increase on day 30, compared to day 1. These alterations were not age dependent. Our data suggest affection of the human visual pathway in MHI. PR-VEP recording seems to be a useful, objective, noninvasive tool, helping to identify possible subclinical affections of the visual pathway in MHI.
对50例轻度头部损伤（MHI）患者在创伤后第1天和第30天记录了图形翻转视觉诱发电位（PR-VEP），并将数据与20名正常人进行比较。所有患者均无视觉主诉。目的是研究MHI中可能存在的视觉通路损伤，并测试PR-VEP作为一种客观无创工具在检测MHI中可能存在的视觉系统亚临床损伤方面的有用性。与正常人相比，P100潜伏期和波幅无显著差异。创伤后第1天和第30天患者数据的比较显示，与第1天相比，第30天潜伏期显著缩短，波幅增加。这些改变与年龄无关。我们的数据表明MHI中人类视觉通路存在损伤。PR-VEP记录似乎是一种有用、客观、无创的工具，有助于识别MHI中视觉通路可能存在的亚临床损伤。
